Essentials - User Interface

Where do I add measurements to a sequence for dynamic scans?

• Routine card

• Contrast card

• Sequence card

• Resolution card

Answer explanation

In the dynamic tab :)

To decrease chemical shift artefact I should

• Decrease bandwidth

• Decrease phase oversampling

• Increase Bandwidth

• Increase phase oversampling

Answer explanation

When turning on iPAT, which of the following are affected?

• SNR

• Field of View

• Spatial resolution

• TE

Answer explanation

To gain SNR in a sequence, I can

• Increase FOV

• Decrease phase oversampling

• Increase spatial resolution

• Turn on iPAT

Answer explanation

Increasing the FOV (while maintaining resolution) will increase the voxel.

Bigger voxel - more proton signal collected

RESTORE can be used to improve?

• Acquisition time

• Chemical shift artefact

• Spatial resolution

• T2 signal

Answer explanation

in T2 and PD sequences ONLY!

Using a lower BW will result in?

• More noise sampled

• Less noise sampled

• Higher SNR

• Lower SNR

Answer explanation

If the patient orientation is registered incorrectly, it can be changed in post processing?

• True

• False

Answer explanation

Do not proceed to scan as image orientation labels  cannot be changed -  even when flipped/rotated
